Re: [9fans] pi vs. older mac keyboard

[Anthony Sorace <a@9srv.net>]

I'm using a new-ish Apple keyboard here. It works well except that (a) about twice a day or so, the control née caps lock key misses a key up event (tapping it again solves it), and (b) the fn key (and therefore the things accessed by it) does nothing.

I originally had all sorts of problems with the thing, including protocol errors and the pi rebooting or freezing, dependent on the order things got plugged in. I then realized I was under-powering the pi. The most common USB power sources put out around 500 mA; the pi wants (from memory) 700-1200 mA, and really seems to be happier at the higher end of that. I went out and got a 2A USB charger and things improved dramatically.
